I continue tweaking my seat ever so slightly getting it closer and closer to ideal. Everything from height, front to back, forward/backward tilt.

I've broken my tail bone several times in my 20s and it's caused me problems ever since. Once I started biking, it's been miserable. Some days it's worse than others. Given my position on the bike, I don't understand how it is putting pressure on my tail bone but apparently something is pressing on something else that is pressing on it. I'll figure out the seat thing at some point...it's getting closer and closer.
